The expansion pedestal cabinet is a modular, freestanding storage cabinet that
is completely self contained with dual fan-cooled power supplies, an internal
UltraSCSI single-ended extender module, and an internal EMU circuit board.
The cabinet dimensions are the same as the subsystem base pedestal which
houses the controller and is normally installed within one meter of the base
cabinet to facilitate the cable connections between the two units. Figure 4–2
shows the expanded subsystem's SBB slots and they are corresponding SCSI
ID addresses. Figure 4–3 shows the items on the rear panel power supplies.
Characteristics of the expansion pedestal cabinet are:
The storage device capacity of the expansion pedestal is seven 3½-in.
SBBs.
The pedestal slots are numbered 0 through 6 from top to bottom.
There are seven SCSI bus device addresses (target IDs) 8 through 14
which can be assigned to the 3½-in SBBs.
